Defining Additional Virtual Disk-to-LUN Mapping

Use the Define Additional Mapping option to define additional  for an existing .

Note: This option can also be used to define the initial virtual disk-to-LUN mapping.

Important:

  • An  mapping is not required for  managed . If the storage array is managed using an out-of-band connection, and an  mapping is assigned to the , an Access Virtual Disk mapping will be assigned to every  created from the Default Group. To prevent this from happening, remove the Access Virtual Disk mapping from the Default Group. For more information, see Removing an Access Virtual Disk Mapping.
  • Most hosts can have 254  mapped per storage partition. Solaris with  and HP-UX 11.0 are restricted to 32 LUNs. If you try to map a  to a LUN that is greater than 32, the host will be unable to access it.
  • An initial mapping of the  or host must be created using the Define Storage Partitioning Wizard before the Define Additional Mapping option can be used.

Use the following procedure to define additional virtual disk-to-LUN mappings:

1

From the Topology pane of the , select the Default Group, Undefined Mappings node, an individual undefined mapping, a host group, or a host. Then, select Mappings >> Define >> Additional Mapping.

2

Select a host group or host to which the virtual disk is to be mapped from the Host group or host drop-down list.

All defined hosts, host groups, and the Default Group are displayed as options.

Note: If a host or host group is selected that does not have a    defined, a warning dialog is displayed.

3

Select a single LUN (0 through 254) from the drop-down list.

Note: Only available LUNs are displayed.

4

Select the virtual disk to be mapped to from the Virtual Disk table. The table lists the names and capacity of the virtual disks that are available for mapping, based on the host group or host selected.

Note: You can include a ??in a partition. However, any hosts that are mapped to this virtual disk will have read-only access to it until it is promoted to a  or until the mirror relationship is removed.

5

Select Add to save the virtual disk-to-LUN mapping, and leave the dialog open.

Note: The Add button remains unavailable until a host group, host, LUN, and virtual disk are selected.

6

Repeat steps 2 through 5 to add multiple additional virtual disks to the storage partition.

Note: Once a virtual disk has been mapped once, it is no longer available in the Virtual Disk table.

7

Select Close to exit the dialog.

The virtual disk-to-LUN mappings are saved. The Topology and Defined Mappings panes in the Mappings View are updated to reflect the additional mappings.
